As of 2025, the anniversary of the Rattanakosin Kingdom remains one of Thailand’s most important cultural and historical celebrations. Every year on April 21, Bangkok marks the founding of its capital — Rattanakosin Island, where in 1782 King Rama I established the Chakri dynasty and moved the capital from Ayutthaya to the opposite bank of the Chao Phraya River.
In 2025, the three-day festivities took place from April 20 to 22 under the patronage of the Ministry of Culture and the Bangkok Metropolitan Administration. Events spanned the historic city center and attracted tens of thousands of visitors and tourists.
History of Rattanakosin
The Rattanakosin Kingdom (Siam) was founded on April 21, 1782. This day marks the beginning of modern Thailand. Rattanakosin Island became the heart of the new capital, home to:
- The Grand Palace
- Temple of the Emerald Buddha (Wat Phra Kaew)
- Temple of the Dawn (Wat Arun)
The anniversary is not just a memorial date, but a reminder of national identity.

Conclusion
Although Rattanakosin was founded 243 years ago, in 2025 it remains alive and breathing with history. When thousands walk streets where royalty once trod, when piphat music echoes and the air smells of Thai sweets, it’s not just a festival — it’s the revival of the capital’s soul. As one organizer said: “We’re not celebrating a date. We’re celebrating the city’s spirit.”
